Summary

holaOS through 2026.822.1 has an authentication bypass by spoofing (CWE-290) in the channel-gateway Telegram connector. The connector authorizes senders by their mutable username instead of only their numeric id. An attacker who registers a released username listed in allowFrom can submit turns to the bound workspace agent, which runs configured tools on the operator's machine. A public exploit is linked in the references.
